People around the U.S. regularly turn to professional-grade devices like home air purifiers to improve the quality of an indoor space. While products such as the IQAir GC MultiGas can go a long way toward clearing the air of many irritants, there is still an ongoing issue with poor air quality in many of the world's cities.
The World Heath Organization recently released a report noting that the pollution in most of the globe's cities does not meet the standards for safe levels. According to the organization's data, only about 12 percent of people who reside in urban environments are exposed to healthy air quality, and the pollution in most places is getting worse.
Living in a polluted city puts people at risk for a host of health problems. WHO recommended implementing new guidelines for monitoring and improving conditions around the world.
"We can win the fight against air pollution and reduce the number of people suffering from respiratory and heart disease, as well as lung cancer," said Dr. Maria Neira, WHO's director for public health, environmental and social determinants of health. "Effective policies and strategies are well understood, but they need to be implemented at sufficient scale."
